Abstract (en)
[origin: US2020279707A1] A relay array may connect an electrical device (e.g., an inverter, power converter, etc.) to a utility grid. Based on a detection of a power interruption or fault, the relay array may disconnect the electrical device from the grid to ensure safety or reduce damage to the electrical device or grid. The relay array may include one or more electromechanical relays (e.g., latching relays). A safety catch may prevent the latching relay(s) from changing states. The electrical device may be configured to facilitate removal of the safety catch once the ability to change states is desired. The latching relay(s) may also be supplied with a power pulse for changing a state of the latching relay(s). The power pulse may be provided by a power bank that may be maintained with power in case of a power interruption or fault.
